 Please comment your favorite ticket numbers you want to ask to discuss with your *SHORT* comment or summary. 
 (your summary/comment will help us because we don't need to read all of ticket comments) 

 *DO NOT* discuss then on this ticket, please. 

 Past meetings: <https://bugs.ruby-lang.org/projects/ruby/wiki#Developer-Meetings> From this time, we use a ticket to make dev-meeting agenda page instead of a wiki page <https://bugs.ruby-lang.org/projects/ruby/wiki#Developer-Meetings>. 

 # NOTE 

 Dev meeting *IS NOT* a decision making place. All decisions should be done at the bug tracker. 
 Dev meeting is a place we can ask Matz, nobu, nurse and other developers directly. 
 Matz is a very busy person. Take this opportunity to ask him. If you can not attend, other attendees can ask instead of you (if attendees can understand your issue). 
 We will write a log about discussion to a file or to each ticket in English. 
 All activities are best-effort (keep in mind that most of us are volunteer developers). 
 The date, time and place is scheduled according to when/where we can reserve Matz's time. 

 # Agenda 

 ## Next dev-meeting 

 ## About 2.6 timeframe 

 ## Carry-over from previous meeting(s) 

 * [Feature #14784] One-sided Comparable#clamp (with endless/startless ranges) (zverok) 
     - more reasonable version of Object#enumerate proposed for the previous meeting. 
 * [Feature #14859] Timeout in VM (normalperson) 
     - Still needs some work, mainly wondering if the idea of moving this part of stdlib into core VM is acceptable or not. No semantic changes except speed improvement.
